In the complex operation system of the power plant, various valve equipment plays a vital role. Z942H-16C electric gate valve is one of the key devices widely used in pipeline systems such as oil and steam. Next, let’s learn how to use Z942H-16C electric gate valve.

1. Preparation before installation

Before installing the Z942H-16C electric gate valve on the corresponding pipeline of the power plant, a series of preparations need to be carried out. First, check the valve to ensure that its appearance is free of damage and defects, and all parts are firmly connected. Carefully check whether the specifications and models of the valve are consistent with the design requirements, including the valve’s caliber, pressure level and other parameters, to avoid problems in subsequent installation and use.

At the same time, prepare the tools and materials required for installation, such as wrenches, sealants, etc. For the installation site, proper cleaning and preparation should also be carried out to ensure that the installation environment is clean and dry, and to avoid contamination or damage to the valve by debris, dust, etc.

2. Installation and operation points

When installing the Z942H-16C electric gate valve, strictly follow the installation instructions and relevant specifications. First, place the valve in the installation position to ensure that the inlet and outlet directions of the valve are correct. Generally, there will be arrow marks on the valve to indicate the flow direction of the medium. The installation must be carried out strictly in the marked direction.

Next, connect the pipeline to the valve. The connection methods usually include flange connection and welding connection. The specific connection method should be selected according to the installation design of the valve and the actual situation on site. During the connection process, ensure that the connection parts are well sealed. Sealing materials such as sealants or gaskets can be used to seal to prevent medium leakage.

At the same time, pay attention to the tightening force of the connecting bolts, which should be uniform and moderate to avoid over-tightening or over-loosening. Over-tightening may cause the bolts to deform or damage the seals, while over-loosening may cause loose connections and leakage. After installation, check and adjust the horizontality and verticality of the valve to ensure that the installation position of the valve is accurate.

3. Debugging of electric devices

The Z942H-16C electric gate valve is equipped with an electric device to achieve remote control and automatic operation. After installation, the electric device needs to be debugged. First, check whether the power connection of the electric device is correct, whether the voltage is stable, and ensure that the power supply is well grounded.

Then, test the remote control function of the electric device. You can send operating instructions through the control system to check whether the opening and closing actions of the valve are normal, whether the actions are accurate, and whether the action process is smooth, without jamming, abnormal noise, etc. At the same time, check whether the feedback signal of the electric device is accurate and whether the control system can correctly display the opening and closing status and position information of the valve.

During the debugging process, the opening and closing displacement setting values of the electric device should be gradually adjusted to ensure that the opening and closing positions of the valve meet the actual operating requirements. At the same time, the protection functions of the electric device, such as overcurrent, overheating, emergency stop, etc., should be tested to ensure that the electric device can automatically stop running under abnormal conditions to protect the safety of equipment and personnel.

4. Operation and precautions during operation

During the normal operation of the Z942H-16C electric gate valve, the operator must strictly follow the operating procedures. When opening and closing, the corresponding operation instructions must be sent to the electric device through the control system, and the next operation can be carried out after the valve moves smoothly and in place.

At the same time, pay close attention to the opening and closing status and operating parameters of the valve, such as the valve opening, medium flow, pressure, etc. If the valve is found to be abnormal, such as unsmooth movement, inaccurate opening, medium leakage, etc., stop the operation in time, and check and repair it.

During operation, the electric gate valve should be inspected and maintained regularly, including checking the appearance of the valve, sealing performance, and operating status of the electric device. For valves that operate in high temperature and high pressure environments for a long time, pay attention to the thermal expansion and deformation of the valve, and make corresponding adjustments or repairs if necessary.
